I would feel confident in this textbooks ability to provide scientifically sound ideas to my students. All chapters are organized into headings and subheadings that are easy to navigate with the tool bar on the left hand side of the interface. For additional free and open resources, visit http://www.openstax.org/. However, I personally find most traditional textbooks a little uninspiring, and I think that by following the standard format closely, this book misses out on an opportunity to improve on a formula that could probably stand to be updated. The paragraphs are small enough to be viewed effortlessly on a mobile device such as a phone or tablet with ease. I focused in on Chapter 15: Genes and Proteins. This book will serve the purpose of introductory biology and could very well be used in place of the expensive textbooks. The text is easy to read as a PDF and in book form. The text reads well and has no grammatical errors. read more. This helps students connect what they are learning with their lives. 2 Review Questions - Biology 2e | OpenStax Review Questions Review Questions Highlights 4. Sources were cited appropriately and they were relatively recent. The OpenStax Biology book has units and chapters that cover all of the major topics that one would consider for a general or introductory Biology course. Otherwise I had no interface issues. There is no adaptive learning software like publishers use. Concepts did not flow one into another. WebAnswer Both systems involve chemical messengers that must interact with receptors in order to have an effect. The depth of content is largely appropriate for a 200-level Biology class. The book is nicely comprehensive in its overall selection of units and chaptersall the basic components of any standard semester-long or year-long general biology course for majors or a mixed nonmajors/majors audience. While it is not as polished as a traditional text, I feel that the advantages it offers far outweigh the costs. So it will remain relevant for the long term, as general biology subjects do not change very much anymore. If you are looking for a majors level textbook that covers all the content covered in the vast majority of first semester biology course, this will work for you. In general, the content of the text is accurate. Reviewed by Sarah Foltz, Assistant Professor, Radford University on 1/14/20, General coverage is good the text covers all of the areas Id expect to see in an introductory biology textbook, including behavior, which I find is sometimes overlooked. As with any textbook, minor errors have made their way into the book. I did not find any obvious examples of insensitive or offensive language. This is a shame and could wind up creating misconceptions about the current study of animal behavior. The variation of individuals within a species is due to genetic factors, environmental factors, and their interactions. The organization of the text will allow for easy updating and revision by authors and users. Protists are another trouble spot, but the authors do a good job discussing the modern perspective on the protists. It is nice that links to animations and webpages are included. I also do not like being required to download some videos through links, but would rather watch the video within the website. I noted several examples in which material is explained clearly in one part of the text, with inaccurate or inconsistent information in other places. I'm not in love with the interface when using the search function when it takes the plae of the TOC. Some examples: At the end of the text, it would have been nice to pair Plant Structure and Function with the plant diversity chapters in the previous unit, and likewise for the Animal Structure and Function. The chapters are divided into topical sections, making it easy to assign or not assign specific topics. I found no major changes between Openstax Biology 1e and 2e. The book is similar in scope to the textbooks mentioned above and follows a conventional topic and chapter sequence, with molecular and cellular topics (plus genetics and evolution) in the first part of the book and the more organismic topics and ecology occupying the rest of the book. This is inevitable to some extent in any text, but the editors have some smoothing out to do. After one semester of using Openstax, I have received positive feedback from students. read more. In every other published textbook, taxonomy is presented first, and it can then be discussed how cladistics is a better approach since it takes relationships into account. A few of these external resources are Flash, which may not be accessible to some students. I very much appreciated the inclusion of Career Connections and Evolution Connections. On page 154, the text states, For example, think about someone opening a bottle of ammonia in a room filled with people. Currently available textbooks have made huge strides in producing carefully rendered and accurate illustrations and animations that are produced by talented teams of artists and animators. There are a few errors or misstatements in this book, but they are few and far between. I've found all the terminology to be consistent. If there are provisions for regular revisions of the textbook these issues can be addressed easily. Nitrogen fixation and plant defenses are not well explained, and deamination and cation exchange dont come up in a search. Many of the key terms are highlighted in bold, but it would be nice if students could click on bold key terms to get definitions. Some of the content, such as mitosis and meiosis, are separated into different chapters, which is different from some of the standard texts used (e.g. In Chapter 8, the text states, The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago. No, fossil fuels formed in the Paleozoic, which ended 252 mya. Here are some examples: For the level of students being targeted, there is sufficient focus. One feature I like is that students can explore these concepts in greater depth by following in-text links to online resources. What happens to the free energy of that original glucose molecule as it is processed through cellular respiration? a. how selective forces change the allele frequencies in a population over time Content is laid out in a clear and concise manner. My attempt to use a QR code scanner app of a mobile phone on the PDF of the textbook on a laptop screen didnt work and clicking the URL indicated the link was no longer current. I did not find references to other sections of the book, and these chapters could be used without the rest of the text. I am seriously considering transitioning to this text from my much more expensive versions that I currently require. However, this may be a students first exposure to such concepts; in such an instance, word choice and grammar leaves one to draw ones own conclusions. It is a scientific text and presents the material in a way that should not be offensive to any one. Details from recent discoveries are always additions I make to the course, and I do not need the most recent findings in my textbook. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. I also like the connections to diet and nutrition throughout Chapters 2 4. Better than most textbooks which have all the questions at the end of each chapter. Wherever technical jargon is used, it is immediately explained so the reader gets used to field terminology but also understands it. Biology 2e works through cellular respiration diligently and thoroughly, making it very useful as a reference text. While the artwork is generally good some of the illustrations are too small and generally not as visually appealing as in commercial textbooks. Reviewed by Robert Sorensen, Professor, Minnesota State University Mankato on 6/10/15, The 8 units this textbook, chemistry through ecology, sufficiently cover the range of topics that would be covered in an Introductory Biology series of courses.The order in which topics are addressed follows the common approach of building from Students really resist having to carry heavy textbook around (I cant blame them) and have expressed that they like the digital version. Many biology textbooks seem to be set up this way and I think this organization makes the material flow well. I felt like there was too much detail on some processes, and too little detail on other topics. Images and figures need revision as many are displaying with poor resolution in the pdf version. As an Amazon Associate we earn from qualifying purchases. This text is a nice way to help students organize those core ideas, all in one place.

How many grams and how many liters of water would have to be evaporated through perspiration to rid the body of the heat generated during two hours of exercise? Also, some of the links to learning dont work, such as for the second part of glycolysis link. New vocabulary is introduced throughout in bold, and key terms are repeated at the end of each chapter. ),Opp.- Vinayak Hospital, Sec-27, Noida U.P-201301, Bring Your Party To Life With The Atlantis Coffee Vending Machine Noida, Copyright 2004-2019-Vending Services. In another comparison, human to yeast sequencing shows a difference in the 44th position. This suggests that humans and yeast are as closely related as humans and rhesus monkeys. Tunicates and vertebrates are sister taxa that diverged more recently. This would have gotten a slightly higher grade had so many labels been misapplied. Reviewed by Mark Wagner, Instructor/Life Sciences, Portland Community College on 6/14/21, I found the book to cover the topics in good depth, definitely a lower division, major-level text - The 'Link to Learning' sections should be in a footnote or sidebar as they are distracting in the main body of the text. I did not see any inaccuracies in my use of the book; however, there were few references available (at least that I could find). In some instances, the language could be simplified to make the text more accessible and terms better defined. Since evolution is such an important theme in Biology and a chosen connecting theme in this book by the authors, Chapter 1 should cover evolution in some detail instead of leaving this essential topic to a later chapter. You can assign students some chapters and not others. I have not encountered grammatical errors in the text. consent of Rice University. Occasionally a link to a video is not available but that is the nature of any online content and instructor should prepare to handle it accordingly. But I confess that I was not look closely at the grammar. Modularity is good! I only viewed the text using a laptop, so I cannot comment on its interface on a smartphone or tablet. Openstax Biology 2e offers a low-cost alternative that meets the needs of an introductory biology class. In general, each Unit/Chapter could stand alone is independent from the textbook as a whole. But it does allow the reader to come to their own conclusion. In fact, throughout the textbook, bacteria are mentioned in contexts where bacteria and archaea should both be included. A glossary of key terms is provided for each chapter. There are some nuances of classification and speaking in generalities that could lead the learner to think in terms of absolutes where that may not be the case (ie. The chapters are clear and concise. However, the likelihood of an instructor assigning those subsections at random is very low, so I don't think it would be a problem. Most chapters lack the highly detailed summary images that most will be familiar with from commercial texts--for example, a summary image of cellular respiration or cladograms for major phylogenies. On page 482, the text states, Although natural selection may work in a single generation on an individual, it can take thousands or even millions of years for the genotype of an entire species to evolve. The idea that evolution and speciation require millennia is included as a misconception later in the chapter! While the textbook appears to be clear to me (someone with a PhD in biology), I wonder if it would be clear to my students? In some places, information is repeated within a paragraph. The Table of contents is easy to access (always on the top navigation bar) and so with a click a student go right to the assigned chapter or section. Yes, my other comments are as follows: The organization of the book is intuitive and I can easily find information and readings associated with class topics through the table of contents. As such the text was lacking in examples and depicting a diverse cultural tone and images when possible. One very serious weakness of this text is the art: the figures, the animations, and the Art Connection features. I felt that the eight major units of the text had a logical flow to them, moving from smaller, discrete concepts to applications and interactions among concepts. The critical thinking questions are generally pretty good. I am reviewing this textbook not for a first year course in introductory biology, but for a second-year one-semester course on the integrative biology of animals. I enjoyed the navigation of the text via the left-hand side contents menu. 1 Review Questions - Biology 2e | OpenStax 4. 11. In a very few places this book might need to be updatedfor example, some of the taxonomic diversity of prokaryotic and eukaryotic groups, and some other statements (for example, there is a lot of life near deep sea vents that does not depend in any way on photosynthesis). Any possible problems can be easily fixed or updated. As noted above, in some cases the art is not consistent across ideas and within and between chapters, and this could be confusing for a student. Notes on Specific Sections anabolic (also anabolism) pathways that require an energy input to synthesize complex molecules from simpler ones. There was also links to videos and tutorials which more fully explained some of the more difficult topics in a visual and/or audio dimension. However, the scientists who are mentioned are the typical examples theres no obvious effort to include or highlight contributions from a variety of cultures or ethnic backgrounds. Perspiration is the body's mechanism for eliminating this heat. Naturally, other chapters addresses some scientific concepts which have unfortunately become politicized (evolution and anthropogenic climate change, for example), which may be alienating to some students. I prefer to have more evolution covered in the first 2 chapters but it is just as easy to jump to chapter 19 to harvest enough info to inform the rest of the cell biology chapters. However, while more topics are covered in the Biology textbook, the amount of comprehensiveness for each Chapter is only minimally expanded from the Concepts of Biology textbook. However, I don't think it goes out of its way make science more accessible. As noted above, the chapters can be covered in any order as instructors prefer, but the overall outline of the units and chapters fits perfectly with any standard biology course taught over one or two terms. Both the pdf and online version contain an index. The sections, though integrated, can, in many cases stand alone as an introduction to the topics.

Each carbon atom can bond with as many as________ other atom(s) or molecule(s). The introduction to scientific approach and the culture of science is generally good. This textbook is mostly suitable for 100 level introductory biology for non-majors. The 8 units this textbook, chemistry through ecology, sufficiently cover the range of topics that would be covered in an Introductory Biology series of courses.The order in which topics are addressed follows the common approach of building from the simplest level of organization up to the highest level. Some of the content, such as mitosis and meiosis, are separated into different chapters, which is different from some of the standard texts used (e.g. On page 486, this sentence is incomplete: Define species and describe how species are identified as different.

Reviewed by Maria Quintero, Graduate teaching assistant, Florida State University on 11/28/18, This seems like a great book for freshman because often at that stage the students are interested in science but are unsure of what branch of science they want to go into. bond formed by a dehydration reaction between two monosaccharides with eliminating a water molecule. This is one area in which this book truly shines: chapters are subdivided and can often stand alone. In some cases, these are not strictly related to biology; for example, quantitative and qualitative are discussed but not defined in Chapter 1. For my purposes, the weakest section is on phylogenetics, but I always need to supplement that section of any text. Their own figure 1.17 underscores that prokaryotes are not a valid monophyletic group. Interactive exercises (links to learning) and visual connection would be well appreciated by the students. The book also includes various types of practice and homework questions that help students understandand applykey concepts. The text is relevant, and it should remain so for some time. Since the text is foundational, many of the subjects aren't changing rapidly. I learned quite a bit myself from reading it, and I look forward to teaching courses where I can use this book's material to help explain concepts in biology. Reviewed by Ken Carloni, Assoc. Because there is so much information to cover in the Introductory Biology survey courses, it is helpful to organize the text in this way so students are not overwhelmed. I navigated to TpT to see your store and noticed you had answer keys for reading guides (Chapter 10 I believe) that are not shared here. I think that the chapter glossaries and ample index do a good job with the jargon. bond formed by a dehydration reaction between two monosaccharides with eliminating a water molecule. are not subject to the Creative Commons license and may not be reproduced without the prior and express written Finally, we biologists also know that there are many humans born intersex, and their existence is completely ignored by the statements made by the authors. This book focuses on proper concepts and details, not extraneous stuff. The major complaint from the students who are non-majors in biology is that the material (at least a large portion of it) has no relevance to their field of study. I also found the instructor resources to be consistent. Journalism, Media Studies & Communications.

As my class has a focus on biotechnology, this will be the first time it is included in a 'general use' textbook. This would be what good instructors always do, but new instructors often have to take more of their clues from the text. This makes it easy to expand on particular topics, replace a section with other reading, and tailor the text to the objectives of a course. I do not understand why it is not more widely adopted. A few are poor. Much of the genetics content that I would use from this book is sort of timeless in that it hasnt changed in many years and is unlikely to change in the near future (meiosis, mitosis, mendelian genetics). The textbook is comprehensive; the extent and depth of the topics and concepts covered are at the level required in an introductory course for biology majors. Also, there is no discussion of applications of next-generation sequencing (e,g, RNA-seq, ChIP-seq) that are commonly used today.
